Definitions

  • the invention relates to a method for operating a continuous caster with a belt casting machine having a stationary mold, which is connected via a roller table to a compensating furnace, and a device for casting strips.
  • EP 0 264 459 B1 discloses a process for producing hot-rolled steel strip from continuously cast slabs, in which the solidified cast strand is separated into sections of the same length and these sections are successively introduced into an oven in which they are stored over a period of time finally to be handed over to a roller table of a rolling mill.
  • the liquefied material for forming the cast strand is cooled in the sheet guide of the continuous casting machine.
  • the exit temperature of the cast strand at the end of the sheet guide is still above 1150 ° C.
  • the cast strand cools down and runs from the roller table at a temperature of approximately 1150 ° C. onto a runway located in the storage furnace.
  • the system required to carry out this process is bound to a defined strand thickness with a corresponding casting speed. Changes in the casting parameters regularly result in production losses, quality reductions and increases in effort.
  • a lowering of the casting speed with constant solidification thickness i.e. if casting rolling is not possible, leads to severe temperature loss due to the additional cooling of the slab in the continuous caster as well as the long dwell time of the strand on its way to the leveling furnace.
  • the cross-cutting system known from this document since no scissors are used here, leads to large radiation losses due to the long process time.
  • the invention has set itself the goal of creating a method with a corresponding device in which the casting parameters of a given production chain, consisting of a continuous casting plant, a compensating furnace and a rolling mill, can be changed with simple means and the casting performance is at least maintained.
  • the invention is based on the knowledge that in the combination of the continuous casting stage with the rolling stage, both in billet, slab and, in particular, thin slab casting, the energy content of the strand in the temperature compensation furnace immediately downstream of the continuous casting installation is of great importance in the roller hearth or transverse transport furnace .
  • the energy content of the slab can be used as a guide variable for operating the entire system when it enters the compensating furnace.
  • the energy content of the slab is adjusted to the desired rolling temperature of the hot strip to be produced when it enters the compensating furnace.
  • the furnace can be operated in such a way that no energy is to be supplied to the strand, but that it is only used to compensate for the slab temperature.
  • Basic design e.g. a solidification thickness of 60 mm at a casting speed of 5 m / min. the solidification thickness of the slab is reduced and the casting speed is influenced, irrespective of the influencing variable such as strand cooling or insulation between the continuous casting machine and the furnace.
  • Another possibility to increase the casting performance combined with a higher heat content of the slab when entering one of the continuous casting plants directly downstream furnace is made possible by casting rolling in the casting machine, ie reducing the casting thickness during solidification.
  • the casting parameters are set in such a way that the slab when the
  • Compensating furnace corresponds to the desired rolling temperature of the hot strip to be produced.
  • the system now makes it possible to increase the casting performance with constant casting thickness and maximum casting speed and to control the heat content of the slab entering the compensating furnace.
  • the parameters are set so that the bottom of the sump is always in the area of the mouth
  • Belt casting machine is located. Depending on the current energy content of the strand immediately behind the continuous casting machine, heat can be drawn from the slab by active cooling, or heat radiation is largely prevented by an insulating device.
  • the casting speed is dependent on the decreasing thickness with the same width of the slab to its maximum value of 7.2 m / min.
  • Casting speed increased the casting capacity is increased from 2.31 to 2.77 t / min., I.e. from 100 to 120%.
  • the casting performance can not only be maintained by this measure, but even increased.
  • the energy content and thus the corresponding average slab temperature rises at the furnace inlet C of 1111 C to 1150 ° C. This temperature increase can lead to the fact that the slab in the area of the roller table in front of the compensating furnace has to be adjusted to the desired slab temperature at the furnace inlet by cooling.
  • Figure 1 A diagram of the continuous caster.
  • Figure 2 A diagram of the slab average temperature as a function of the casting speed.
  • Continuous casting machine 10 The continuous casting machine 10 is followed by a roller table 21, which produces the shortest possible connection, for example a length of 10 m, to the compensating furnace 50.
  • a transverse transport furnace 51 is provided in the upper part of the picture and a roller hearth furnace 52 is provided in the lower part of the picture.
  • insulating hoods 32 and cooling elements 31 are provided in the area of the roller table 21 in the upper part of the picture and cooling elements 31 for influencing the heat content of the slab.
  • the continuous casting machine 10 has a metallurgical length of 9.3 m, the roller table 21 has a length of 10 m, the slabs are separated by a cross cutting device 22 to a length of about 43 m, so that the cross transport furnace 51 has a length of around 45 m and the roller hearth 52 has a length of 150 m.
  • a conventional rolling mill 60 for producing hot strips of 1 mm thickness is connected to the equalizing furnace 51 or 52.
  • the equalizing furnace 51 or 52 For example, consist of a one- or two-stand preliminary stage with a subsequent winding station and finishing train.
  • the standard situation is in a) with a basic design of a solidification thickness of 60 mm at the entrance of the compensating furnace, which is provided 10 m away from the end of the continuous caster, and a casting speed of 5 m / min. designed. Approx. 0.3 to 0.5 l water / kg steel spray water is cooled in the continuous casting machine until the slab at the end of the machine
  • the casting speed is increased more than would be the case with an increase with a constant thickness of the slab, brought to its maximum value and taking into account the setting of the sump tip at the end of the machine, a temperature increase occurs, in the present case 1150 ° C. Entry into the equalization furnace expected (point h)). If this temperature is too high for the desired rolling process, heat can be extracted from the strand by cooling.

Abstract

L'invention concerne un procédé de fonctionnement d'une installation de coulée continue comportant une machine de coulée continue pourvue d'une lingotière fixe (11), qui est reliée à un four (50) par l'intermédiaire d'une ligne de rouleaux (21). Une fois le format des brames déterminé à la sortie de la lingotière parmi les paramètres de coulée on ajuste au moins la vitesse de coulée de manière qu'au moment où elle entre dans le four (50), la brame présente la température de laminage voulue de la bande à laminer à chaud et que le cratère liquide se trouve toujours dans la zone d'embouchure de la machine de coulée continue. Des mesures visant à influer sur la teneur en énergie thermique de la brame après qu'elle soit sortie de la machine à coulée continue sont prises. L'invention concerne en outre la machine de coulée continue qui permet de mettre ledit procédé en ÷uvre.
